  4. diploid parents produce diploid offspring Diploid cells have two copies of each chromosome: one copy from the mother and one from the father • Animals are diploid and usually reproduce sexually. • do not have free-living haploid life stages

  5. Homeotic genes control early development. Hox genes determine the position of cells differentiation. A Hox gene mutation leads to the development of a body structure in the wrong position. • Most animals have Hox genes.
